The GCF would be C. 3mn

Step-by-step explanation:

If you look at both numbers, 3m^2n and 12mn^2, you can factor out (divide both numbers by) 3, m, and n.

It will most definently be C

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

b.my answer is b.
